The strongest counters to a Spy are the Scout and Pyro.

However, the sniper can still be killed in three shots or less with the Spy's revolvers, making it almost useless against smarter spies. Snipers can use the Razorback to defend themselves from a single backstab and briefly preventing any Spy foolish enough to attempt it from attacking or switching weapons. Snipers are obvious Spy targets due to their reduced movement speed and tunnel vision when scoped in with their Sniper Rifles. Medics are a valuable target since their healing and uber make their entire team stronger, and are also usually behind their teammates leaving them vulnerable to backstabs. The Heavy is the slowest class, to begin with, and is even slower when he has one of his mini-guns revved up – this slower-moving speed, along with the distraction of combat and a high health pool, makes for an easy and valuable backstab. Three other common Spy targets are the Heavy, Medic, and Sniper. He can also make use of enemy teleporters to surprise (and maybe even telefrag) his foes. Using his sappers, he can disable the Engineer's buildings – slowly draining their health until they are destroyed unless removed by either an Engineer or a Pyro wielding the Homewrecker, Maul, or Neon Annihilator. His disguises prevent Sentry Guns from targeting him and allow him to heal and recharge cloak from enemy dispensers. In addition to being able to assassinate key enemies quickly and efficiently, the Spy has advantages over the Engineer. In a dream the Scout had, the Spy is his birth father, which was later confirmed in the TF2 comic The Naked and the Dead. The Spy seems to have a romantic relationship with the Scout's mother, though it still remains a mystery on how and why they know each other well. Moreover, he seemed to have taken etiquette classes, which explains on how he acts like a gentleman really well. It's a mystery on how he became a master spy and a master of disguise as no one knows if someone trained him or he rather he trained himself. Not much is really known about his past but all that is known is that he was born in France in an unknown region. Much like the Pyro, the Spy is one of the most mysterious mercenaries on the team, as both his identity and name are unknown.
